An automated reasoning code for the damage assessment of protective structures (DAPS) is being developed within the Air Force. Protective structures in this context will be synonymous with buried facilities which are designed to withstand intense impulsive pressures. The code is being written for initial implementation on a microcomputer IBM AT. Two inferencing schemes, both involving back-chaining logic, are being investigated for the DAPS code. DAPS combines crisp numerical data with non-crisp linguistic data using the precepts of fuzzy set theory to estimate the uncertainty in the knowledge base. The data base comes from a series of eleven experimental tests on buried reinforced-concrete boxes subjected to explosive pressures. Crisp data in the form of instrumentation waveforms and linguistic data obtained from experts through questionnaires dealing with the experimental tests comprise the knowledge base.
